Use a texture. It saves polygons and it's easier.
Make it so that your logo thing is on the same plane as the face it's supposed to be on, as opposed to just floating above it.
You could make it a print brick, then do some simple code to automatically set the print as that specific one when the brick is planted
The recycle logo is unfortunately too big, if I had put it on the exactly same plane, after a distance it will bug the forget up. It's not recommended to have visible faces overlap.
You can arrange faces on that side around the logo so there's no overlap.
